Original application filed October 1922, srielle, 597,467. Divided and this application 111494V August '22', 1923'. Serial No. 653,701.

heating plant of any suitable kindY tok serve.

as a substitute or auxiliary heatproducing agency, together with means for directing a current of air through the heater to facilitate distribution of the heated air throughout the heating. plant.

Another object of' the invention is to arrange a plurality of electrical heating ele-A ments in, spaced' relation, and in substantial parallelism with. a current of air under pressure directed` therepast for effectively heat'- ing such air together with means for spreading and distributing the air kover the heating elements.

Other'objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will. be best understood by reference to the accompanying drawings forming a part of this specification, and in which, y

Figr 1 is avertical section'A ofthe invention, showing parts thereof in full lines;

Fig. 2 is a sectional view of.' the invention, on the line 2-21ofi Fig. 1;

Fig. 3 is a sectional View of the invention on theli'ne 3-3 of Fig. 1'; and

Fig.V 4. is a sectional view of; the invention on the line lt ofFig. 1;

The heater contemplated herein is primarily intended'as a substitute or auxiliary device adapted to be interposed'` in, or connected with, heat'distributing systems of various types of heating plants, and may be connected with the casing of ay furnace, with a single iiue, if desired, or other suitable portion of the heating plant.

The present application is directed to the heater per se as contra-distinguished from the heater used in conjunction with the heat distributing system of a heating plant, which forms the subject matter of my application, Serial No. 597,467, filed October 28, 1922, of which this case 1s a division.

Referring tothe drawings, represents a fragment of a furnace' casing, though it is' obvious that any other' suitable portion of the .heat distributing system maybe utilized, as above explained; 11 represents a suitable connection which communicates with the interior of a` heater 12. The heater 12 preferably comprises a hoodv 13 having a chamber 14, such hood. being preferablyV detachably mounted upon a somewhat larger body portion 15 having a chamber 16l therein, suchy body 'i portion bein mounted upon a suitable pedestal` 17. rhe pedestal 17 is provided with a base. 18 having a flange 19, adapted to support a housing 20, preferably of asbestos, which incloses theV heater 12.

Mounted in theupper portion ofthe chamber 16 isa frame 21, which is preferably in the form of a cross. Such frame may be provided with suitable apertures 22 adapted to accommodate elongated heating elements 23, such heating elements each being provided with ar flange 24, adapted torest upon thev frame 21 so as to suspend the heating elements 23 in the chamber 16 as shown. The heating elements 23 each comprises a body of insulating material haying coils 25 of resistant Wire thereon, said elements pref erably being connected in parallel by the wires 26v and 27,V suchwires extending outwardly through the housing 20 and: being connected with a suitable source of current (not shown).

The pedestal 17 is provided with an inver-ted` conical chamber 28, at the mouth of which is mounted a plate 29 having a plurality of` spaced perforations 30 therein. The inner end of ther chamber 28 communicates with a bore 31, in the pedestal 17, and with aconduit 32, which may be connected to a compressed. air tank 33 provided with a suitable pump 34 and 'motor 35 for driving the same.. If desi-red, instead of the` compressed air outfit,-an ordinary blower fan (not shown) might be used. The bore 31. may be provided with any suitable valve for regulating the passage of air through the conduit 32 and the heater 12. As shown, a valve 36 is slidably mounted in the bore 31 such valve preferably having a stem 37 upon which is provided a rack 38 adapted to be engaged by a pinion 39, mounted upon a shaft 40 extending to the outside of the housing 20.

By this arrangement a current of air un- 'der pressure is directed throughthe heater,

such current of air being controlled by the Y valve, and spread by the conical chamber prising a circular body portion characterand the loutletV openings to receive '28 and plate 27 so as to pass between and around a plurality of spaced electrical heating elements, and being heated thereby be- Vfore' passage into the heat distributing sysdesire to avail myself. of such variations and- Y A n modifications as come withinv the scope or Y the appended claims.V

Having described my invention what I claim as-new and desire to secure by Letters Patent is: f.

1. VAyheater of the class described comprising a circular body portion characterized by havingcoiicaved walls,'an air inlet andan air outlet for said body portion, lo-.

cated in .opposed relation at the ends of said concaved walls, and heatingelements disposed in cross formation between the inlet directly along two fronts the air deflected from said concavedk walls.

2. A heater of the class described coinizedl by liavingconcaved walls, an air inlet and airfoutlet for said body portion, located in opposed relation at the ends of said vconcaved walls, kparallel heating elements dis-V posed in cross formation between the :inlet and the Outletopenings to receive directly.

along two fronts the air deflected from said concaved walls, a conical member having its largerfendiii communication with said inlet opening, and means for directing a vcurrent of air into said conical nieinber.- Y

3. A vheater of the class described comprising a Vcircular body portion characterized by having concaved walls, an air inlet and Van air outlet for said body portion, located in opposed relation at the ends of said concaved walls, parallel heating elements disposed in cross formationbetween. the Vinlet andthe outlet openings .to'receive directly along two fronts the air deflected from said concaved walls, a conical member having its larger end in communication with said inlet opening, means for directing a current of air into said conical member, and. a hood having a discharging passage surrounding said air outlet.V Y K 4C. A heater of the class described comprising Ya circular body portion having central reduced top and bottoni openings and flanged, a pedestal on which the body ,portion is supported, secured to the bottom ange, there being a cavity in said pedestal and a flared passageleading to said bottom opening,'ineaiis for forcibly introducing air into said cavity, a Vframe arranged vwithin the flange around the .top opening, and a plurality of heating elements arranged. in cross formation depending fromvsaid frame.

tion is supported secured to vthe bottom flange, there beiiig'a cavityvin said pedestal and a. flared passage leading to said bottom.

opening, means for forcibly introducingair into said cavity, a valve operative in said cavity for controlling the flow ofV air into said passage, a framefarranged within Vthe flange at the top opening, a plurality of heating elements arranged in cross formation depending from said frame, and a hood 5. A heaterfof the class described com-If prising .a circular bodyy portionhaving Vcen- Atral reduced top and bottom Yopenings and anged, ay pedestal onwhich the body portion is supported, secured to the bottom4 l flange, there being a cavityrin said pedestal and a flared passage leading to saidbottoni opening, said pedestal having a base, means Y for forcibly introducing air into said cavity, a frame arranged within the flange at the top opening, a plurality of heaters arranged in cross formation depending. from said frameA and a housing mounted on said base and enveloping'said circular body portion and said pedestal.
